ne n knwn that. I, ISAAC H. vA'N Wm, f clarksville, in the county-of Albany and State of 'N ew York,

f have invented'a certain new and useful Improvement in Hollow Angers of which thefollowing is a full, clear,

l and exactdescriptiomreference being had tothe accompanying drawing, which makes part of this specifi- Figure lirepresents a planview; Figure 2, a longitudinal central section through the 'ame, at the line a: :t o`f `fig`.`4', the knives Vbeing left in place; and A x Figurefl, an end view. l i 1 My invention belongs to that class of angers used -in forming tapering tenons, and is designed more especially for` forming or shaping the ends of wooden axle-trees; and f I The improvement consists in a hollow frame, A,

of a cone, extending into a shank, A', properly formed for the application of power,fand having slots at intervals oblique to its longitudinal axis, for the reception of kuives'B B, the leading one of which has its advance end formed into a cutting-edge or knife, G

The knives may bemade adjustable by'means of "slots and set-screws, in any wellfknown way.

A knife, D,is let into the base ofthe frame adepth equal to the thickness thereof', and secured in place by means of a screw passingthrougha hole in the knife,

and entering the frame. Sniiicient throat is provided for the escape of chips from each knife.

The operation is as follows: v The'joist for the axle-tree, having its ends tapered `sniiciently to enter the bore for a short distance, the

angerl is then placed upon one end so formed, and power applied to` the shank A by means of a'brace or other suitable mechanism, and, as it is turned to the right, the knives C and D cnt away the wood in con-` tact therewith, and as the anger advances, and the wood enters therein, the knives B B give it the form required. k r, I am aware Vthat hollow angers have long been in Y use, and'` therefore do not broadly claim such device;

` neither do I claim the knives arranged obliqnely to the longitudinal axis of the angers; but

That I do claim as my invent-ion, and desire to secure by Letters Patent, isf TheA combination of the frameAand its shank, with theknives 13 Brand D, as 4described and shown, for the a purpose set forth.
